CMail's MAIL FROM overflow

when the server is issued a too long argument to the 'MAIL FROM'
command, like :

MAIL FROM: AAA[...]AAA@nessus.org

Where AAA[...]AAA contains more than 8000 'A's.

This problem may permit a possible hacker to prevent this host
to act as a mail host and may even permit him to execute
